AXIS 233D - Video Streams  
13  
Video Streams  
The AXIS 233D provides several different video stream formats. The type you choose to  
use depends on your requirements and on the properties of your network.  
The Live View page in the AXIS 233D provides access to Motion JPEG and MPEG-4 video  
streams, as well as to single JPEG images. Other applications and clients can also access  
these video streams/images directly, without going via the Live View page.  
Stream Types  
Motion JPEG  
This format uses standard JPEG still images in the video stream. These images are then  
displayed and updated at a rate sufficient to create a stream that shows continuous motion.  
The Motion JPEG stream uses more bandwidth, but also provides excellent image quality  
and access to every individual image contained in the stream.  
Note also that multiple clients accessing Motion JPEG streams can use different image  
settings.  
MPEG-4  
This is a video compression standard that makes good use of bandwidth, can provide high  
quality video streams at less than 1Mbit/s.  
Notes: • MPEG-4 is a licensed technology. The AXIS 233D includes one viewing client license. Installing addi-  
tional unlicensed copies of the viewing client is prohibited. To purchase additional licenses, contact  
your Axis reseller.  
• All clients viewing the MPEG-4 stream must use the same image settings.  
The MPEG-4 standard provides scope for a large range of different coding tools for use by  
various applications in different situations, and the AXIS 233D provides certain subsets of  
these tools. These are represented as Video object types, which are selected for use with  
different viewing clients. The supported video object types are:  
• Simple - sets the coding type to H.263, as used by QuickTime™, for example.  
• Advanced Simple - sets the coding type to MPEG-4 Part 2, as used by AMC  
(AXIS Media Control).  
When using MPEG-4 it is also possible to control the bit rate, which in turn helps control  
bandwidth usage. CBR (Constant Bit Rate) is used to achieve a specific bit rate by varying  
the quality of the MPEG-4 stream. When using VBR (Variable Bit Rate), the quality of the  
video stream is kept as constant as possible, at the cost of a varying bit rate.

MPEG-4 protocols and communication methods  
To deliver live streaming video over IP networks, various combinations of transport  
protocols and broadcast methods are employed.  
• RTP (Realtime Transport Protocol) is a protocol that allows programs to manage  
the real-time transmission of multimedia data, via unicast or multicast.  
• RTSP (Real Time Streaming Protocol) serves as a control protocol, to negotiate the  
transport protocol to use for the stream. RTSP is thus used by a viewing client to  
start a unicast session. See below.  
• UDP (User Datagram Protocol) is a communications protocol that offers limited  
service for exchanging data in a network that uses the Internet Protocol (IP). UDP  
is an alternative to the Transmission Control Protocol (TCP). The advantage of  
UDP is that when there is network congestion packets can be dropped without  
slowdown of the live stream since the protocol does not require delivery of all  
data. This is suitable for live video, as there is no point in re-transmitting old  
information that will not be displayed anyway.  
• Unicasting is communication between a single sender and a single receiver over a  
network. This means that the video stream goes independently to each user, and  
each user gets their own stream. A benefit of unicasting is that if one stream fails,  
it only affects one user.  
• Multicast is a bandwidth-conserving technology that reduces bandwidth usage by  
simultaneously delivering a single stream of information to multiple network  
recipients. This technology is used primarily on delimited networks (intranets), as  
each user needs an uninterrupted data flow and should not rely on network rout-  
ers.  
How to stream MPEG-4  
Deciding on the combination of protocols and methods to use depends on your viewing  
requirements, and on the properties of your network.  
RTP+RTSP  
This method (actually RTP over UDP and RTSP over TCP) should be your first  
consideration for live video, especially when it is important to always have an up-to-date  
video stream, even if some images do get dropped. This can be configured as multicast or  
unicast.  
Multicasting provides the most efficient usage of bandwidth, especially when there are  
large numbers of clients viewing simultaneously. Note however, that a multicast broadcast  
cannot pass a network router unless the router is configured to allow this. It is thus not  
possible to multicast over the Internet, for example.

AXIS 233D - Video Streams  
15  
Unicasting should be used for video-on-demand broadcasting. However, if more and more  
unicast clients connect simultaneously, the server at some point becomes overloaded.  
There is also a maximum of 20 simultaneous viewers to be considered.  
RTP/RTSP  
This unicast method is RTP tunneled over RTSP. This can be used to exploit the fact that it  
is relatively simple to configure firewalls to allow RTSP traffic.  
RTP/RTSP/HTTP or RTP/RTSP/HTTPS  
These two methods can also be used to traverse firewalls. Firewalls are commonly  
configured to allow the HTTP protocol, thus allowing RTP to be tunneled.  
The AXIS Media Control  
The recommended method of accessing live video (MPEG-4 and/or Motion JPEG) from the  
AXIS 233D is to use the AXIS Media Control (AMC) in Internet Explorer. This ActiveX  
component is automatically installed on first use, after which it can be configured by  
opening the AMC Control Panel applet from the Windows Control Panel. Alternatively,  
right-click the video image in Internet Explorer.  
Other methods of accessing the video stream  
Video/images from the AXIS 233D can also be accessed in the following ways:  
• If supported by the client, the AXIS 233D can use Motion JPEG server push to  
display video. This option maintains an open HTTP connection to the browser and  
sends data as and when required, for as long as required.  
• As single JPEG images in a browser. Enter the path:  
http://<ip>/axis-cgi/jpg/image.cgi?resolution=CIF  
• Windows Media Player. This requires AMC and the MPEG-4 decoder. The paths  
that can be used are listed below, in the order of preference.  
• Unicast via RTP: axrtpu://<ip>/mpeg4/media.amp  
• Unicast via RTSP: axrtsp://<ip>/mpeg4/media.amp  
• Unicast via RTSP, tunneled via HTTP: axrtsphttp://<ip>/mpeg4/media.amp  
• Unicast via RTSP, tunneled via HTTPS: axrtsphttps://<ip>/mpeg4/media.amp  
• Multicast: axrtpm://<ip>/mpeg4/media.amp

Other MPEG-4 clients  
Although it may be possible to use other clients to view the MPEG-4 stream, this is not  
guaranteed by Axis. For some other clients, such as QuickTime™ the Video Object Type  
must be set to Simple, under Video & Image > Advanced > MPEG-4. It may also be  
necessary to adjust the advanced MPEG-4 settings. To access the video stream from  
QuickTime™ the following path can be used:  
rtsp://<ip>/mpeg4/media.amp  
This path is for all supported methods, and the client negotiates with the network camera  
to determine which transport protocol to use.  
Note: <ip> = IP address of the AXIS 233D.

Overlay image limitations  
Image Formats  
Image Size  
• If the image overlay and text overlay are larger  
than the video image, no overlay is displayed.  
When also using a text overlay, this occupies  
16 pixels in height and as many in width as  
the video image.  
• Windows 24-bit BMP (full color) The height and width of the overlay  
image in pixels must be exactly  
divisible by 4.  
• Windows 4-bit BMP (16 colors)  
• OS/2 4-bit BMP (16 colors)  
• If the overlay is initially positioned so that  
part of it is outside the video image, it is relo-  
cated so that it appears over the video image,  
i.e. the entire image is always displayed.  
• The maximum overlay image size supported by  
the AXIS 233D is the same as the maximum  
image resolution. See Technical Specifications,  
on page 66.

Advanced Camera Settings  
To optimize the lighting settings according to your requirements, modify the following  
settings under Lighting Conditions:  
• Color level, Brightness and Sharpness - Find the level that best suits your image  
needs by testing.  
• Exposure area - This setting determines which part of the image is used to  
calculate the exposure.  
• IR cut filter - To improve image quality in low-light conditions for example at  
night, set the IR cut filter to Off to allow IR light. In daylight, the IR cut filter  
should be set to On to block IR light. Using the default Auto setting, the camera  
automatically switches between On and Off according to the current lightning  
conditions. The image is shown in black & white when the IR cut filter is off.  
Note: The Auto setting is only possible when the iris is set to Auto Iris, and the exposure control is set to Auto-  
matic.  
• Wide dynamic range - Corrects the exposure when the contrast between light  
and dark in an image is extreme. Test the different levels to find the one that  
works best for your light conditions.  
• Backlight compensation - This setting is used to make the subject appear clearer,  
such as against a bright background.

Low Light Behavior  
The settings for Low Light Behavior determine how the camera behaves at low light levels.  
These settings affect video image quality and frame rate.  
• Exposure control - This setting is used to adapt to the amount or type of light  
used. Automatic is the default setting and can be used in most situations. The  
shutter speed is automatically set to produce optimum image quality. Use Manual  
if you have special requirements for the exposure setting. Allow slow shutter can  
be enabled/disabled when the exposure control is set to Automatic.  
• Max exposure time - Increasing the exposure time will improve image quality,  
but at the expense of the frame rate. There may also be an increase in motion  
blur.  
• Max gain - Measured in decibels (dB). A high level of amplification may provide  
a better image in very low light situations.  
Please use the online help files  
for more information.  
Image Settings  
• Autofocus enabled (default setting).  
• Stabilizer - When monitoring an environment that is subject to vibrations (such  
as traffic control) images can appear unsteady. To improve image quality, choose  
High frequency if the vibrations in your environment have high frequency, or  
choose Low frequency if the vibrations have low frequency.  
• Image freeze on PTZ - Choose All movements from the drop-down list to freeze  
the image during camera movement. Once the camera reaches its new position  
the current image is shown. Presets freezes the image only when the camera  
moves between preset positions.  
MPEG-4 Settings  
Tools for adjusting the MPEG-4 settings and for controlling the video bit rate.  
The MPEG-4 standard provides several coding tools for different applications and different  
situations. As most MPEG-4 clients do not support all of these tools, one usually defines  
and uses subsets for different clients or group of clients. Under Client Compatibility, select  
the settings appropriate for your viewing client.  
The bandwidth used by the MPEG-4 stream can be controlled by adjusting the maximum  
bit rate and setting the bit rate type to variable or constant.

MJPEG settings  
Sometimes the image size is large due to low light or complex scenery. Adjusting the  
maximum frame size helps to control the bandwidth and storage used by the MJPEG video  
stream in these situations. Defining the frame size as Unlimited provides consistently good  
image quality at the expense of increased bandwidth and storage usage during low light  
conditions. Limiting the frame size reduces bandwidth and storage usage, but gives poor  
image quality. The maximum frame size should be set to an optimal value in order to  
prevent excessive bandwidth and storage usage, please refer to the online help files  
more information.

AXIS 233D - Audio  
24  
Audio  
The AXIS 233D can transmit audio to other clients by connecting an external microphone  
and can play audio received from other clients via a connected speaker.  
Basic Audio Settings  
This section describes how to configure the basic audio settings for the AXIS 233D, for  
example, setting the audio mode and adjusting the sound levels in the microphone and  
speaker connected to the camera.  
Enable Audio  
Check this box to enable audio.  
Audio Channels  
The AXIS 233D has four types of audio transmission. Choose the type that best suits your  
needs.  
Audio mode  
• Full Duplex mode transmits and receives audio streams simultaneously in both  
directions. This means that you, for example, can talk and listen, or play and  
record audio, at the same time.  
• Half Duplex mode transmits and receives audio in both directions, but only in  
one direction at a time. This means that you must select when to receive or trans-  
mit audio with the push-to-talk button. To speak, press and hold the button  
(check that the microphone is not muted). When you have finished speaking,  
release the button and you will receive audio from the other end of the connec-  
tion.  
Note: The push-to-talk button is configured from AMC. It is also possible to configure the push-to-talk button so

that it toggles between the speaking and listening modes.  
• When selecting Simplex - Network Camera speaker only mode, the speaker con-  
nected to the camera plays audio, but no audio is transmitted from the camera to  
other web clients. This could be used for providing spoken instructions to a per-  
son seen in the camera. This mode requires you to use the push-to-talk button.  
• Simplex - Network Camera microphone only mode transmits audio from the  
AXIS 233D to web clients. It will not receive audio from any other web client.  
This can be used in remote monitoring, and web attractions, to provide live audio,  
as well as video of a monitored situation.  
When using Half-Duplex, the option Send the sound from the active client to all other  
clients, transmits the audio signal from the client that is talking to all the other clients.  
Audio Input  
Audio from an external microphone or a line source can be connected to the Audio in  
Power/Audio connector of the AXIS 233D, see I/O terminal connector blocks, on page 58.  
The audio source must be set to Microphone or Line depending on the connected device.  
When Microphone is selected as a Source, set the Input sensitivity to High for a passive  
(unamplified) microphone, for example a computer mic or clip-on mic. Set to Low for a  
microphone with a built-in line amplifier.  
The Enable microphone power option provides DC power for an external microphone. If  
using a small electret condenser microphone such as a clip-on or PC microphone, this  
option needs to be enabled.  
Note: To use a high impedance dynamic microphone, DC power should be disabled. DC power will not harm the  
microphone, but if you are uncertain, try switching it off and on. The default value is DC power enabled. To  
use a professional microphone requiring 48V phantom power, you need an external power supply and you  
must use a balanced-unbalanced converter (audio transformer) in-between.  
If there are problems with the sound input being too low or high, adjust the input gain for  
the microphone attached to the AXIS 233D.  
Select the desired audio Encoding format; G711 or G726.  
Depending on the selected encoding, set the desired audio quality (Bit rate). The settings  
depend on the available bandwidth and the required audio quality.  
The AXIS 233D can be set to trigger an event if the incoming sound level rises above, falls  
below or passes the set value. The Alarm level is set between 0-100%.  
Audio Output  
If the sound from the speaker is too low or high, adjust the output gain for the active  
speaker attached to the AXIS 233D.  
When satisfied with the settings, click Save. Click Reset to revert to the old settings.  
Note: To receive synchronized video and audio, it is recommended that the time settings in the camera and client  
PC are synchronized with an NTP Server. This is enabled in the camera under System Options > Date &  
Time. Please refer to the online help pages for more information.

AXIS 233D - Audio  
26  
Advanced Audio  
Advanced audio settings can improve audio quality by speech filtering and echo and noise  
cancellation.  
When enabled, the speech filter reduces noise by filtering out all frequencies below 100Hz  
and above 3500 Hz. This improves sound quality if a person is close to the microphone  
when talking and reduces background noises.  
Enable echo cancellation to reduce acoustic echoing that can be caused by audio coming  
from a speaker and captured by a microphone.  
Noise cancelling is a way of reducing the background noise if the microphone is set up in  
a noisy environment and you are only interested in hearing a person who is talking close  
to the microphone. The noise canceller attenuation produces maximum noise reduction  
when set to 18dB of attenuation. Optimize the sound quality by listening to the sound and  
adjusting the attenuation level as required.  
When satisfied with the settings, click Save. Click Reset to revert to the old settings.

AXIS 233D - Live View Config  
31  
HTML Examples  
You can add live video from the AXIS 233D to your own web site. The camera can  
transmit a Motion JPEG stream to up to 20 simultaneous connections, although an  
administrator can restrict this to fewer. If MPEG-4 is set as video format, multicasting is  
used and the audio and video stream will be available for an unlimited number of viewers  
connected to the parts of the network where multicast is enabled. Please note that a  
separate MPEG-4 license is required for each viewer.  
Select the preferred Video format from the drop down list. The available options are  
Motion JPEG, MPEG-4 using AMC and MPEG-4 using QuickTime.  
The Motion JPEG selection has additional settings for Image type, Image size and other  
Optional settings to configure the video stream to suit your web page.  
Click Update once satisfied.  
The camera generates the required source code for your configuration. Copy this code and  
paste it into your own web page code.  
External Video  
An external video source is a source originating from some other Axis device on the  
network. The images from these sources can be displayed just as if they were produced by  
the AXIS 233D.  
The External Video Source List shows all of the external video sources currently  
configured. The information displayed is the source's name and the path to the video  
stream. Up to 20 external video sources can be configured.  
Working with External Video Sources  
1. To add a new video source, click the Add button. This opens the External Video  
Source Setup dialog, which is used to make all the necessary settings.  
2. To modify an existing video source, select it and click the Modify button.  
3. To delete an external video source, select it and click the Remove button.  
Sequence Mode  
Sequence Mode is a configuration that automatically displays the view from multiple,  
previously defined preset positions (see Dome Configuration, on page 32 and the online  
help  
) and external video sources (see above).  
This is useful for security personnel viewing a surveillance system that constantly rotates,  
in the listed order or at random, through the selected preset positions and video sources.  
To set up a sequence mode, simply select the desired preset positions and/or video sources  
and enter the number of seconds or minutes to display each one for. Each position or video  
source can be displayed for up to 59 minutes.

Dome Configuration  
Preset Positions  
32  
A preset position is a pre-defined camera view than can be used to quickly move the  
camera to a specific location.  
From Preset Position Setup, use the Pan, Tilt and Zoom (PTZ) controls to steer the camera  
to the required position. When satisfied with the camera's position, enter a descriptive  
name. The camera position, iris and focus settings are then saved as a preset position.  
This position can be assumed at any time,  
by selecting the preset's name from the  
Preset positions drop-down list. Preset  
positions can be selected in Live View, in  
Event Types, in Sequence Mode and in  
the Guard Tour.  
One position can be set as the Home  
position, which is readily accessible by  
clicking the Home button in both the  
Preset Position Setup window and the  
Live View window. The position's name  
will have (H) added, for example, Office  
Entrance (H).  
The AXIS 233D can also be configured to return to the Home position when the camera  
has been inactive for a specified length of time. Enter the length of time in the field Return  
to home when inactive and click Save.  
See Overlay Settings, on page 19, for information about including the preset position name  
in the overlay image text.  
Auto Tracking  
The AXIS 233D can detect movement in the camera’s field of view, for example a moving  
vehicle or person. If auto tracking is enabled, the camera will automatically pan and tilt to  
follow the moving object or, in case there is lots of simultaneous movement, the area with  
the most movement. Auto tracking continues until the moving object stops or disappears  
from the monitored area. Movement in areas blocked by privacy masks and in exclude  
areas does not trigger auto tracking.  
Note: It is strongly recommended to enable the PTZ Control Queue if Auto Tracking and Guard Tour are simulta-  
neously enabled. In the PTZ Control Queue, the Guard Tour has lower priority than Auto Tracking so the  
camera will not abandon Auto Tracking to start a Guard Tour.

Medium is usually a good choice, but in some situations a low or high sensitivity might be  
more suitable, depending on the size of the moving objects and the image contrast.  
Exclude Areas  
Exclude areas are areas where movement is to be ignored. Note that movement in an area  
blocked by a Privacy Mask is always ignored.  
To create an exclude area, click Add area. The area (the blue rectangle) can be resized and  
moved to the desired position. Enter a descriptive name and click Save. To enable or  
disable an area, click the name of the area and click the Enable/Disable button.  
Max Limits  
The pan and tilt limits restrict the area where auto tracking is allowed. This may prove  
useful, for example, to avoid tracking birds in the sky. Click Enable Tilt Limit and Enable  
Pan Limit to enable the pan and tilt limits, respectively.  
Enter the limits (in degrees) of the Lower tilt angle and Upper tilt angle, or click the links  
and move the blue horizontal bars in the preview window. To set the pan limits, enter the  
values (in degrees) in the Pan Limit Start and Pan Limit End fields, or click the links and  
move the blue vertical bars in the preview window. Auto tracking is allowed between the  
pan start and end limits going clockwise, see the illustration below.

Guard Tour  
A guard tour displays preset positions, one-by-one, in a pre-determined order or at  
random, and for configurable time periods. Once a preset position has been set and added  
to the guard tour, the following settings can be made:  
• Move Speed - sets the speed of the Pan/Tilt movements to the preset position.  
• View Time in seconds or minutes.  
• View Order (or Random).  
OSDI Zones  
On-screen Direction Indicator (OSDI) Zones can be included in the overlay text to aid the  
user to navigate the camera. Each OSDI Zone is set up with coordinates and a descriptive  
name.  
The camera uses the coordinates of the center of the image to set the lower left and upper  
right zone areas. First navigate to where you would like the lowermost left point of the  
OSDI Zone to be located. By clicking the Get button the coordinates are set. Proceed to  
where the upper right point of the zone should be located and click its Get button. Give the  
zone a descriptive name and click Ok. See Overlay Settings, on page 19, for information  
about including the name of the OSDI Zone in the overlay text.  
Advanced  
Limits  
Define the pan, tilt, zoom and focus limits for the AXIS 233D. Movements to the left and  
right, up and down, can be restricted to narrow the area under surveillance. The near focus  
limit can be set to avoid focusing on objects too close to the camera.  
Note: Once a limit has been saved, this position cannot be exceeded by the AXIS 233D unless the values have  
been reset and saved to a greater value first (reset the default values of the mechanical restrictions).  
Move speed sets the speed of the camera's Pan/Tilt movements. The default setting is  
maximum speed.  
Controls  
Shortcut command buttons can be created to provide direct access to various commands  
provided by the AXIS 233D. The buttons are then displayed in the PTZ Panel which is  
available on the Live View page by clicking Ctrl Panel (see page 10). Axis’ VAPIX® API  
allows you to create your own commands. For more information go to www.axis.com

AXIS 233D - Event Config  
37  
Event Types  
An Event Type is a set of parameters  
describing how and when the  
Network Dome Camera is to perform  
certain actions.  
Example: If a door is opened, and an event  
has been configured to act on this, the Network  
Dome Camera can record and save video images  
to an FTP server or send a notification email to a  
pre-configured email address with a pre-config-  
ured message. Video images can be sent as an  
attachment with the email.  
Triggered Event  
A triggered event can be activated by:  
• A signal from external equipment connected to an input port on the camera, for  
example a pushbutton.  
• A manual action such as clicking the Manual trigger button on the Live View  
page. Events can also be triggered manually via the product’s API (Application  
Programming Interface).  
• Movement in a motion detection window.  
• A rise or fall of the sound level.  
• Restart (reboot), for example after power loss.  
• Temperature outside the operating range of the camera. This could for example  
indicate problems with the outdoor housing.  
• PTZ preset positions.  
• Auto tracking.  
How to set up a triggered event  
This example describes how to set the Network Dome Camera to upload images when the  
main door is opened:  
1. Click Add triggered on the Event Types page.

buffer, enter the desired length of time  
and specify the required image frequency.  
Include post-trigger buffer - Contains  
images from the time immediately after  
the trigger. The post-trigger buffer is  
configured in the same way as the  
pre-trigger buffer.  
Notes: • If the pre- or post-buffer is too large for the internal memory, buffering is disabled and an error is written  
to the unit’s log file.  
• Pre-trigger and post-trigger buffers will be lost if the connection to the event server fails.  
Continue image upload (unbuffered) - Enable the upload of images for a fixed length of  
time. Specify the length of time for the uploaded recording, in seconds, minutes or hours,  
or for as long as the trigger is active. Finally, set the desired image frequency to the  
maximum or to a specified frame rate. The frame rate is the best possible, but might not be  
as high as specified, especially if uploading via a slow connection.

Referrals - To prevent unauthorized clients from including the video stream from the  
cameras into external web pages, check the Referrals checkbox and enter the IP address or  
host name of the computer that hosts the web pages with the included video stream.  
Several IP addresses/host names can be defined and are separated by semicolons (;). This  
option only applies to Motion JPEG video streams.  
Notes: • If the referrals feature is enabled and you wish to also allow normal access to the Live View page, the  
product's own IP address or host name must be added to the list of allowed referrers.  
• Restricting referrers has no effect on an MPEG-4 video stream. To restrict an MPEG-4 stream, IP address  
filtering must be enabled.  
• Restricting referrers is of greatest value when not using IP address filtering. If IP address filtering is used,  
then the allowed referrers are automatically restricted to those allowed IP addresses.  
HTTPS  
For greater security, the AXIS 233D can be configured to use HTTPS (Hypertext Transfer  
Protocol over SSL (Secure Socket Layer)). That is, all communication that would otherwise  
go via HTTP will instead go via an encrypted HTTPS connection.  
Certificate - To use HTTPS for communication with the AXIS 233D, a certificate must be  
created. A self-signed certificate can be created in the network camera, but this does not  
guarantee the same level of security as an official certificate issued by a Certificate  
Authority (CA). A CA issues and manages security credentials and public keys for message  
encryption. To create a certificate follow the instructions below:  
1. Click either Create self-signed certificate or Create Certificate Request and enter  
the required information in the provided fields.  
2. Click OK.  
3. Create self-signed certificate generates and installs a certificate which displays  
under Installed Certificate.  
Create Certificate Request generates a PEM formatted request which you copy and  
send to a CA for signing. When the signed certificate is returned, click Install signed  
certificate... to install the certificate in the AXIS 233D.  
4. Set the HTTPS Connection Policy for the administrator, operator and viewer to  
enable HTTPS connection (set to HTTP by default)  
Please refer to the home page of your preferred CA for information on where to send the  
request. For more information, please refer to the online help files

IEEE 802.1X  
IEEE 802.1X is an IEEE standard for port-based Network Admission Control. It provides  
authentication to devices attached to a network port (wired or wireless), establishing a  
point-to-point connection, or, if authentication fails, preventing access on that port.  
802.1X is based on EAP (Extensible Authentication Protocol).  
In a 802.1X enabled network switch, clients equipped with the correct software can be  
authenticated and allowed or denied network access at the Ethernet level.

AXIS 233D - System Options  
44  
Clients and servers in an 802.1X network may need to authenticate each other by some  
means. In the Axis implementation this is done with the help of digital certificates  
provided by a Certification Authority (CA). These are then validated by a third-party  
entity, such as a RADIUS server, examples of which are Free Radius and Microsoft Internet  
Authentication Service.  
To perform the authentication, the RADIUS server uses various EAP methods/protocols, of  
which there are many. The one used in the Axis implementation is EAP-TLS  
(EAP-Transport Layer Security).  
The AXIS network video device presents its certificate to the network switch, which in turn  
forwards this to the RADIUS server. The RADIUS server validates or rejects the certificate  
and responds to the switch, and sends its own certificate to the client for validation. The  
switch then allows or denies network access accordingly, on a pre-configured port.

which then replies to the switch.  
3. The switch forwards the RADIUS server’s CA certificate to the video device, which  
also replies to the switch.

RADIUS (Remote Authentication Dial In User Service) - AAA (Authentication,  
Authorization and Accounting) protocol for applications such as network access or IP  
mobility. It is intended to work in both local and roaming situations.  
CA servers - In cryptography, a Certification Authority (CA) is an entity that provides  
signed digital certificates for use by other parties, thus acting a trusted third party. There  
are many commercial CAs that charge for their services. Institutions and governments may  
have their own CA, and there are free CAs available.  
Date & Time  
Current Server Time - displays the current date and time (24h clock). The time can be  
displayed in 12h clock format in the Overlay Images (see below).  
New Server Time - Select your time zone from the drop-down list and check the daylight  
saving time changes, if desired.  
From the Time mode section, select the preferred method to use for setting the time:  
• Synchronize with computer time - sets the time from the clock on your com-  
puter.  
• Synchronize with NTP Server - the network camera obtains the time from an  
NTP server every 60 minutes. Specify the NTP server's IP address or host name.  
Note: If using a host name for the NTP server, a DNS server must be configured under TCP/IP settings. See Net-  
work > Advanced TCP/IP Settings below.  
• Set manually - this option allows you to manually set the time and date.  
Date & Time Format Used in Images - specify the formats for the date and time (12h or  
24h) displayed in the Live View video streams.  
Use the predefined formats or use your own custom date and time formats. See File  
Naming & Date/Time Formats in the help files  
for information on how to create your  
own file formats.

IP Address Configuration  
The AXIS 233D supports both IP version 4 and IP version 6. Both versions may be enabled  
simultaneously, and at least one version must always be enabled.  
When using IPv4, the IP address for the AXIS 233D can be set automatically via DHCP, or  
a static IP address can be set manually.  
If IPv6 is enabled, the AXIS 233D receives an IP address according to the configuration in  
the network router.  
Notes: • DHCP is a protocol for automatic IP address assignment on a network. IP address assignment via DHCP may  
lead to the situation where the IP address changes and you lose contact. Configure the options for  
notification of IP address change (under Services) to receive notification from the network camera when  
the IP address changes.  
• Alternatively, if your DHCP server can update a DNS server, you can access the AXIS 233D by host name  
which is always the same, regardless of the IP address.  
For more information, please refer to the online help files  
.
Services - Enable ARP/Ping setting of IP address - The IP address can be set using the  
ARP/Ping method, which associates the unit's MAC address with an IP address. Check this  
box to enable the service. Leave disabled to prevent unintentional resetting of the IP  
address.  
Notes: • The ARP/Ping service is automatically disabled two minutes after the unit is started, or as soon as an IP  
address is set.  
• Pinging the unit will still be possible when this service is disabled.  
Options for notification of IP address change - If the IP address for the camera changes  
automatically by DHCP, for example, you can choose to be notified of the change. Click  
Settings... and enter the required information.  
AXIS Internet Dynamic DNS Service - Use this free service to assign a user-friendly host  
name for easy access to your camera (requires Internet access). Click Settings... to register

name is usually the same as the assigned DNS Name. It is always the first part of a Fully  
Qualified Domain Name and is always one word, with no period. For example, myserver is  
the host name in the Fully Qualified Domain Name myserver.mycompany.com  
The Enable dynamic DNS updates allows you to alias a dynamic IP address to a static host  
name, allowing your camera to be more easily accessed from various locations on the  
Internet. Outside users can always access your server using the associated DNS name  
regardless of the WAN IP. The DNS server used by the user and/or the DNS server  
responsible for the domain in use must support RFC2136 and allow updates from the AXIS  
233D.  
The TTL (Time To Live) value determines how long (in seconds) the reply from the DNS  
server should be remembered when checking that the domain name for the registered IP  
address is still valid. For more information, please see the online help

Link-Local IPv4 Address  
This is enabled by default and assigns an additional IP address to the AXIS 233D for use  
with UPnP™. The AXIS 233D can have both a Link-Local IP and a static/DHCP-supplied IP  
address at the same time - these will not affect each other.  
HTTP  
The default HTTP port number (80) can be changed to any port within the range 1 - 65535.  
This is useful for simple port mapping.  
HTTPS  
If applicable, enter the HTTPS port the AXIS 233D will use. The default setting (443) can be  
changed to any port within the range 1024-65535. HTTPS is used to provide encrypted  
web browsing.  
NAT traversal (port mapping) for IPv4  
A broadband router allows devices on a private network (LAN) to share a single connection  
to the Internet. This is done by forwarding network traffic from the private network to the  
“outside” i.e. the Internet. Security on the private network (LAN) is increased since most  
broadband routers are pre-configured to stop any attempts to access the private network  
(LAN) from the public network/Internet.  
Use NAT traversal when your AXIS 233D is located on an intranet (LAN) and you wish to  
make it available from the other (WAN) side of a NAT router. With NAT traversal properly  
configured, all HTTP traffic to an external HTTP port in the NAT router is forwarded to the  
camera.  
LAN (intranet)  
WAN (Internet)  
Broadband  
(NAT)  
router  
ISP  
Notes: • For NAT traversal to work, this must also be supported by the broadband router.  
• The broadband router has many different names: “NAT router”, “Network router“, “Internet Gateway”,  
“Broadband sharing device” or “Home firewall” but the essential purpose of the device is the same.  
Enable/Disable - When enabled, the AXIS 233D attempts to configure port mapping in a  
NAT router on your network, using UPnP™. Note that UPnP™ must be enabled in the  
camera (see System Options > Network > UPnP).  
Use manually selected NAT router - Select this option to manually select a NAT router  
and enter the IP address for the router in the field provided.

If a router is not manually specified, the AXIS 233D will automatically search for NAT  
routers on your network. If more than one router is found, the default router will be  
selected.  
Alternative HTTP port - Select this option to manually define an external HTTP port. Enter  
the port number in the field provided. If no port is entered here, a port number is  
automatically selected when NAT traversal is enabled.  
Notes: • An alternative HTTP port can be used/be active even if NAT traversal is disabled. This is useful if your NAT  
router does not support UPnP and you need to manually configure port forwarding in the NAT router.  
• If a manually selected port is already in use, another will automatically be selected.  
• When the port is selected automatically it is displayed in this field. This can be changed by entering a new  
port number and clicking Save.  
FTP  
The FTP server running in the AXIS 233D enables the upload of new firmware, and user  
applications, for example. Check the box to enable the service.  
RTSP  
The RTSP protocol allows a connecting client to start an MPEG-4 stream. Check the box to  
enable the service and enter the RTSP port number to use. The default setting (554) can be  
changed to any port within the range 1024-65535.  
Network Traffic  
Connection Type - The default setting for the Ethernet interface is Auto-negotiate, which  
means that the correct speed is automatically selected. If necessary, you can set the  
connection mode by selecting it from the drop-down list.  
Maximum bandwidth - To reduce the impact on other services running on your network,  
it is possible to configure the maximum network bandwidth the network camera will be  
allowed to use.  
Specify, in Mbit/s or kbit/s, the maximum bandwidth allowed, or set to Unlimited. This is a  
useful function when connecting your network camera to busy or heavily loaded networks.  
Note: When using MPEG-4 as the video format, remember that setting a maximum bandwidth value here may  
create problems for individual video streams if the maximum value is less than the sum of the bit rates set  
for the video streams. See also the MPEG-4 settings and help available from Setup > Video & Image >  
Advanced. The lowest value allowed for the maximum bandwidth is 30 kbit/s. Using a lower value will leave  
the bandwidth unlimited.

SOCKS  
SOCKS is a networking proxy protocol. The AXIS 233D can be configured to use a SOCKS  
server to reach networks on the other side of a firewall/proxy server. This functionality is  
useful if the AXIS 233D is located on a local network behind a firewall, but notifications,  
uploads, and alarms need to be sent to a destination outside the local network (such as to  
the Internet).  
SOCKS Settings - Check the checkbox to enable SOCKS. Specify the host name or IP  
address of the SOCKS server, the server port and server type (SOCKS4 or SOCKS5). If  
SOCKS5 is used, enter a user name and password. List the networks that are not required to  
go via the SOCKS server under Local networks.  
QoS (Quality of Service)  
Quality of Service (QoS) provides the means to guarantee a certain level of a specified  
resource to selected traffic on a network. Quality can be defined as a maintained level of  
bandwidth, low latency and few packet losses, for example. The main benefits of a  
QoS-aware network can be summarized as:  
• The ability to prioritize traffic and thus allow critical flows to be served before  
flows with lesser priority.  
• The ability to control the amount of bandwidth an application may use and thus  
control over bandwidth races between applications resulting in greater reliability  
in the network.  
The QoS in Axis network video products marks the data packets for various types of  
network traffic originating from the product. This makes it possible for network routers  
and switches to reserve a fixed amount of bandwidth for these types of traffic. The types of  
traffic marked by the camera are video, audio, event/alarm and management network  
traffic.  
QoS Settings - For each type of network traffic supported by your Axis network video  
product, enter a DSCP (Differentiated Services Codepoint) value. This value is used to mark  
the traffic’s IP header. When the marked traffic reaches a network router or switch, the  
DSCP value in the IP header tells the router or switch the type of treatment to apply to this  
type of traffic, for example, how much bandwidth to reserve for it.  
Note that DSCP values can be entered in decimal or hex form, but saved values are always  
shown in decimal. Valid values are integers between 0 and 63. For more information on  
Quality of Service, please see the Axis support web at http://www.axis.com/techsup  
SMTP (email)  
Enter the host names or addresses for your primary and secondary mail servers in the  
fields provided, to enable sending of notifications and image/video email messages from  
the camera to predefined addresses via SMTP.

If your mail server requires authentication, check the box for Use authentication to log in  
to this server and enter the necessary information. Several different methods of  
authentication are available. For more information, please see the online help  
.
SNMP  
The Simple Network Management Protocol (SNMP) allows remote management of network  
devices. Depending on the level of security required, select the version of SNMP to use. The  
three levels of security are:  
• SNMP V1 - includes no security.  
• SNMP V2c - uses very simple security. The community name can be specified as a pass-  
word for read or read/write access to all supported SNMP objects. The community is the  
group of network devices using SNMP.  
• SNMP V3 - provides encryption and secure passwords. HTTPS must be enabled.  
UPnP™  
The camera includes support for UPnP™, which is enabled by default. If also enabled on  
your computer, the camera is automatically detected and a new icon added to “My  
Network Places” (Windows XP/ME) or to a corresponding location.  
Note: UPnP must also be enabled on your Windows XP or ME computer. To do this, open the Control Panel from  
the Start Menu and select Add/Remove Programs. Select Add/Remove Windows Components and open  
the Networking Services section. Click Details and then select UPnP as the service to add.  
RTP / MPEG-4  
Set port numbers and IP addresses for the video and audio streams. The port range is the  
range of ports from which audio and video ports are selected. For multicast streams, only  
certain port numbers and IP addresses should be used. The Time to live value tells the  
network router when to discard IP packets what have not been delivered. For more  
information, please see the online help  
.
Bonjour  
The AXIS 233D includes support for Bonjour. When enabled the camera is automatically  
detected by operating systems and clients that support Bonjour. Enter a descriptive name  
for the camera in the Friendly name field. The friendly name will be displayed in operating  
systems supporting Bonjour.  
Ports & devices  
The AXIS 233D supports 4 input and 4 output ports for external equipment. Each port can  
be given a descriptive name and its Normal state can be set to Open circuit or Grounded  
circuit.  
A port is inactive as long as its Normal state equals its Current state. The port is active  
when the Current state differs from the Normal state.

AXIS 233D - I/O terminal Connectors  
56  
I/O terminal Connectors  
The AXIS 233D Network Dome Camera has three (8 pin) connectors. The inputs/outputs are  
used in applications for example, event triggering, time lapse recording, alarm notification  
via email, picture storage to FTP locations etc.  
• Power, auxiliary power, GND and audio.  
• Four solid state relay outputs - these can drive a maximum load of 50VDC or  
35VAC at 500mA directly or heavier loads by connecting additional relay cir-  
cuitry. If the output is used with an external relay, a diode must be connected in  
parallel with the load for protection against voltage transients.  
• Four alarm inputs - Used for connecting external alarm devices and triggering  
images for specific alarm-based events. The input is typically connected to a  
motion detector or any other external security device, and images can be  
uploaded whenever the detector is activated. A maximum 40VDC is allowed on  
the inputs.

AXIS 233D - Troubleshooting  
Troubleshooting  
Checking the Firmware  
60  
One of your first actions when troubleshooting a problem should be to check the firmware  
version. The latest version may contain a correction that fixes your particular problem. See  
the support section at http://www.axis.com/techsup for information on the latest  
available firmware. The current software version in your AXIS 233D is available from the  
product web pages under Setup > Basic Configuration.  
Updating the Firmware  
The firmware is software that determines the functionality of the AXIS 233D. When you  
upgrade to the latest available firmware from the Axis web site, your Axis product receives  
the latest available functionality. Always read the upgrade instructions and release notes  
available with each new release, before upgrading the firmware.  
New firmware can be uploaded to the AXIS 233D over the network.  
Note: Preconfigured and customized settings are retained for use when the new firmware is running (providing  
that the features are available in the new firmware) although this is not guaranteed by Axis Communica-  
tions.  
1. Save the firmware file to your computer. The latest version of the AXIS 233D  
firmware is available free of charge from the Axis web site at  
http://www.axis.com/techsup or from your local distributor.  
2. Go to Setup > System Options > Maintenance in the AXIS 233D web pages.  
3. In the Upgrade Server section, click Browse to locate the desired firmware file on  
your computer. Click Upgrade.  
Note: After starting the process, you should always wait at least 20 minutes before restarting the AXIS 233D,  
even if you suspect the procedure has failed.

AXIS 233D - Troubleshooting  
61  
Emergency Recovery Procedure  
If power or the network connection to the AXIS 233D is lost during the upgrade, the  
process will fail and the unit will become unresponsive. When the status indicator flashes  
red it indicates a failed upgrade. To recover the unit, follow the steps below. The serial  
number is found on the label on the product casing and was included on an extra label  
included in the package.  
1. Unix/Linux - From the command line, type the following:  
arp -s <IP address of AXIS 233D> <Serial number> temp  
ping -s 408 <IP address of AXIS 233D>  
Windows - From a command/DOS prompt, type the following:  
arp -s <IP address of AXIS 233D> <Serial number>  
ping -l 408 -t <IP address of AXIS 233D>  
Note: The ping -l command is the lower-case letter (L).  
2. If the unit does not reply within a few seconds, restart it and wait for a reply. Press  
CTRL+C to stop Ping.  
3. Open a browser and type in the AXIS 233D’s IP address. In the page that appears, use  
the Browse button to select the upgrade file to use, for example, axis233d.bin. Then  
click the Load button to restart the upgrade process.  
4. After the upgrade is complete (1-10 minutes), the unit automatically restarts and  
shows a steady green (for about 10 seconds) on the status indicator before returning  
to its normal unlit status.  
5. Reinstall the AXIS 233D.  
If the emergency recovery procedure does not get the AXIS 233D up and running again,

Symptoms, Possible Causes and Remedial Actions  
Problems setting the IP address  
Using ARP Ping  
The IP address must be set within two minutes after the power has been applied to the AXIS  
233D, restart the camera and try again. Also, make sure the ping length is set to 408. See the  
ARP ping description in the installation section.  
The AXIS 233D is located on a  
different subnet  
If the IP address intended for the AXIS 233D and the IP address of your computer are located  
on different subnets, you will not be able to set the IP address. Contact your network adminis-  
trator for an IP address on the same subnet as the computer you are performing the installation  
from.  
The IP address is being used by Disconnect the power from the AXIS 233D.  
another device Run the Ping command (in a Command/DOS window, type ping and the IP address of the unit).  
If you receive: Reply from <IP address>: bytes = 32; time = 10 ms..... - this means that the IP  
address may already be in use by another device on your network. You must obtain a new IP  
address and reinstall the unit.  
If you receive: Request timed out - this means that the IP address is available for use with your  
AXIS 233D. In this case, check all cabling and reinstall the unit.  
The AXIS 233D cannot be accessed from a web browser  
Cannot log in If the AXIS 233D has been configured to use HTTPS, check that the protocol in the URL used to  
access the unit is correct. You may need to type this in manually (i.e. http or https) in the  
browser’s address field.  
The IP address has been changed 1) Move the AXIS 233D to an isolated network or to one with no DHCP or BOOTP server. Set the  
by DHCP  
IP address again, using AXIS IP Utility or the ARP Ping command.  
2) Access the unit and disable BOOTP and DHCP in the TCP/IP settings. Return the unit to the  
main network. The unit now has a fixed IP address that will not change.  
3) As an alternative to 2), if dynamic IP address via DHCP or BOOTP is required, select the  
required service and then configure IP address change notification from the network settings.  
Return the unit to the main network. The unit will now have a dynamic IP address, but will  
notify you if the address changes.  
Other networking problems  
Test the network cable by connecting it to another network device, then Ping that device from  
your workstation. See instructions above.  
Cannot send notifications, uploads, alarms, etc, to a destination outside the local network  
Firewall protection The AXIS 233D can be configured to use a SOCKS server to reach networks on the other side of  
a firewall/proxy server. See SOCKS, on page 50 for more information.  
Your AXIS 233D is accessible locally, but not externally  
Firewall protection

Video Image Problems  
Image too dark or too light.  
Problems uploading own files  
See the online help files on Video & Image Settings  
There is only limited space available for the upload of your own files. Try deleting one or more  
existing files, to free up space.  
Missing images in uploads  
Slow image update  
This can occur when trying to use a larger image buffer than is actually available. Try lowering  
the frame rate or the upload period.  
Configuring e.g. pre-buffers, hi-res images, high frame rate etc will reduce the performance of  
the AXIS 233D.  
Slow performance  
Slow performance may be caused by e.g. heavy network traffic, many users with access to unit,  
low performing client, use of features such as Event handling., Image rotation.  
Bad snapshot images  
Display incorrectly configured on In Display Properties, configure your display to show at least 65536 colors, i.e. at least 16-bit.

Using only 16 or 256 colors on your display will produce dithering artifacts in the image.  
Problems with the MPEG-4 format  
Lower frame rate than expected. Check with the administrator that there is enough bandwidth available. Check also the settings  
for bit rate control, in the Video & Image > Advanced > MPEG-4 settings. Using an inappro-  
priate video object type can also affect the frame rate. See the online help for more informa-  
tion.

AXIS 233D - Technical Specifications

General performance considerations  
When setting up your system, it is important to consider how various settings and  
situations will affect performance. Some factors affect the amount of bandwidth (the bit  
rate) required, others can affect the frame rate, and some will affect both. If the load on the  
camera’s CPU reaches its maximum, this will also affect the frame rate.  
The following factors are among the most important to consider:  
• High image resolutions and/or lower compression levels result in larger images.  
Bandwidth affected.  
• Access by large numbers of Motion JPEG and/or unicast MPEG-4 clients. Band-  
width affected.  
• Simultaneous viewing of different streams (resolution, compression) by different  
clients. Frame rate and bandwidth affected.  
• Accessing both Motion JPEG and MPEG-4 video streams simultaneously. Frame  
rate and bandwidth affected.  
• Heavy usage of event settings affects the CPU load on the camera. Frame rate  
affected.  
• Heavy network utilization due to poor infrastructure. Bandwidth affected.  
• Viewing on poorly performing client PC’s lowers perceived performance. Frame  
rate affected.  
Optimizing your system  
To see the bandwidth and frame rate currently required by the video stream, the AXIS  
233D provides a tool that can be used to display these values directly in the video image.  
To do this, special format strings are added as part  
of a text overlay. Simply add #r (average frame  
rate in fps) and/or #b (average bandwidth in Kbps)  
to the overlay.  
For detailed instructions, please see the online help  
for Video & Image > Overlay Settings, and the  
help for File Naming & Date/Time Formats.  
Important!  
• The figures displayed here are the values as delivered by the camera. If other restrictions are  
currently in force, (bandwidth limitation, for example) these values might not correspond to those  
actually received by the client.  
• For Motion JPEG, these values will only be accurate as long as no frame rate limit has been specified.

Frame rates  
Motion JPEG  
Test results show the frame rates in frames/second (fps) for Motion JPEG streams from the  
AXIS 233D, using a compression level of 50% is 25 fps for PAL and 30 fps for NTSC. Note  
that these values are only guidelines - actual values may vary.  
MPEG-4  
Test results show the frame rates in frames/second (fps) for MPEG-4 streams from the AXIS  
233D is 25 fps for PAL and 30 fps for NTSC. Note that these values are only guidelines -  
actual values may vary.  
The MPEG-4 test conditions:  
• Compression level = 50%  
• Video Object Type = Advanced Simple  
• GOV structure = IP*  
* The GOV structure can take two different forms; I and IP. The I-structure sends complete images (I-images)  
whereas the IP-structure mostly sends the differences compared with the previous image (P-images) and only a few  
I-images. The IP-structure requires much less bandwidth than the I-structure.  
Bandwidth  
As there are many factors affecting bandwidth, it is very difficult to predict the required  
amounts. The settings that affect bandwidth are:  
• the image resolution  
• the image compression  
• the frame rate  
• the MPEG-4 object type  
• the MPEG-4 GOV structure  
There are also factors in the monitored scene that will affect the bandwidth. These are:  
• the amount of motion  
• the image’s complexity  
• the lighting conditions.  
For MPEG-4, if there is only limited bandwidth available, and if this is more important  
than the image quality, using a constant bit rate (CBR) is recommended. Use a variable bit  
rate (VBR) if the image quality needs to be maintained at a higher level. With multiple  
viewers, and if supported on the network, consider also using MPEG-4 multicasting, as the  
bandwidth consumption will be much lower.

Glossary  
Active Speaker - a speaker with a built-in power  
AXIS Camera Management - A powerful and efficient  
installation and management tool for Axis network video  
products. The tool can automatically find and set IP  
addresses, show connection status and manage firmware  
upgrades of multiple devices.  
amplifier.  
ActiveX - ActiveX is a standard that enables software  
components to interact with one another in a networked  
environment, regardless of the language(s) used to create  
them. Web browsers may come into contact with ActiveX  
controls, ActiveX documents, and ActiveX scripts.  
ActiveX controls are often downloaded and installed  
automatically as required.  
Bitmap - A bitmap is a data file representing a  
rectangular grid of pixels. It defines a display space and  
color for each pixel (or “bit”) in the display space. This  
type of image is known as a “raster graphic”. GIFs and  
JPEGs are examples of image file types that contain  
bitmaps. Because a bitmap uses this fixed raster method,  
it cannot easily be rescaled without losing definition.  
Conversely, a vector graphic image uses geometrical  
shapes to represent the image, and can thus be quickly  
rescaled.  
AMC (AXIS Media Control) - AMC is the ActiveX  
component required to view moving images from an Axis  
video device in Internet Explorer. The component is  
installed automatically on the viewing computer on first  
use. Once installed, AMC can be configured from  
Windows Control Panel.  
Bit rate - The bit rate (in kbit/s or Mbit/s) is often referred  
to as speed, but actually defines the number of bits/time  
unit and not distance/time unit.  
Analog video camera - The signal from an analog video  
camera is viewed directly on e.g. a monitor in the analog  
system, which depends on traditional analog cabling.  
Alternatively, the signal can be digitized with the use of a  
video server, and can then be made available over a data  
(IP) network.  
Bonjour - Also known as zero-configuration networking,  
Bonjour enables the automatic discovery of computers,  
devices, and services on IP networks. Bonjour allows  
devices to automatically discover each other without the  
need to enter IP addresses or configure DNS servers.  
Bonjour is developed by Apple Computer Inc.  
ARP (Address Resolution Protocol) - This protocol is used  
to associate an IP address to a hardware MAC address. A  
request is broadcast on the local network to discover the  
MAC address for an IP address.  
BOOTP (Bootstrap Protocol) - A protocol that can  
automatically configure a network device (give it an IP  
address). BOOTP is the basis for a more advanced network  
management protocol, the Dynamic Host Configuration  
Protocol (DHCP).  
ARTPEC-2 (Axis Real Time Picture Encoder) - A chip  
designed by Axis for image compression. ARTPEC  
supports a range of CCD and CMOS sensors, built-in  
functionality for sharpening, backlight compensation,  
noise reduction and white balance, support for multiple  
Motion-JPEG streams, support for MPEG-4 part 2, up to  
30 frames/second from 4 simultaneous video sources and  
real-time compression of up to 45 Megapixels/second.  
CCD (Charged Coupled Device) - This light-sensitive  
image device used in many digital cameras is a large  
integrated circuit that contains hundreds of thousands of  
photo-sites (pixels) that convert light energy into  
electronic signals. Its size is measured diagonally and can  
be 1/4”, 1/3”, 1/2” or 2/3”.  
ASIC (Application Specific Integrated Circuit) - A circuit  
designed for a specific application, as opposed to a  
general purpose circuit, such as a microprocessor.  
CCTV (Closed Circuit Television) - A CCTV system is a  
closed/private video system, usually constructed with  
coaxial cabling, and used within a single building/group  
of buildings. It is used to visually monitor the location for  
security or industrial purposes. Video from the CCTV  
system can be recorded and viewed on-site or remotely.  
Aspect ratio - A ratio of width to height in images. A  
common aspect ratio used for television screens and  
computer monitors is 4:3. High-definition television  
(HDTV) uses an aspect ratio of 9:16.  
CCTV video camera - A traditional CCTV video camera is  
an analog camera, available in both monochrome (black  
and white) and color. Cameras can be set in fixed  
positions or placed on “Pan/Tilt/Zoom” devices, which  
allow the camera to be maneuvered. Using a zoom lens  
provides a closer view of the object being viewed. CCTV  
analog video cameras can be viewed over a computer  
network by using a video server.  
Autoiris (DC-Iris) - This special type of iris is electrically  
controlled by the camera, to automatically regulate the  
amount of light allowed to enter.  
AXIS Internet Dynamic DNS Service - This free service  
provides an Axis network product with a unique DNS or  
domain name (URL address), which can then be used  
instead of an IP address to access the product from a web  
browser.  
CGI (Common Gateway Interface) - A specification for  
communication between a web server and other (CGI)  
programs. For example, a HTML page that contains a form

is submitted.  
centrally manage the assignment of Internet Protocol (IP)  
addresses to network devices in a network.  
CIF (Common Intermediate Format) - CIF refers to the  
analog video resolutions 352x288 pixels (PAL) and  
352x240 pixels (NTSC). See also Resolution.  
DHCP uses the concept of a “lease” or amount of time that  
a given IP address will be valid for a computer. The lease  
time can vary, depending on how long a user is likely to  
require the network connection at a particular location.  
Client-server - Client-server describes the relationship  
between two computer programs in which one program,  
the client, makes a service request from another program,  
the server, which fulfils the request. Typically, multiple  
client programs share the services of a common server  
program. A web browser is a client program that requests  
services (the sending of web pages or files) from a web  
server.  
DHCP also supports static addresses for e.g. computers  
running web servers, which need a permanent IP address.  
DIP switch - A DIP switch is an electric switch that is  
packaged in a group in a standard dual in-line package  
(DIP).  
DNS (Domain Name System) - DNS is used to locate and  
translate Internet domain names into IP (Internet  
Protocol) addresses. A domain name is a meaningful and  
easy-to-remember name for an Internet address. For  
example the domain name www.example.com is much  
easier to remember than 192.0.34.166. The translation  
tables for domain names are contained in Domain name  
servers.  
CMOS (Complementary Metal Oxide Semiconductor) - A  
CMOS is a widely used type of semiconductor that uses  
both negative and positive circuits. Since only one of the  
circuit types is on at any given time, CMOS chips require  
less power than chips using just one type of transistor.  
CMOS image sensors also allow processing circuits to be  
included on the same chip, an advantage not possible  
with CCD sensors, which are also much more expensive to  
produce.  
Domain server - Domains can also be used by  
organizations that wish to centralize the management of  
their (Windows) computers. Each user within a domain  
has an account that usually allows them to log in to and  
use any computer in the domain, although restrictions  
may also apply. The domain server is the server that  
authenticates the users on the network.  
Coaxial cable - Coaxial cable is the standard means of  
transmitting analog video in a CCTV system. Coaxial is  
also used by cable companies to distribute television in  
residential buildings.  
Codec - In communications engineering, a codec is  
usually a coder/decoder. Codecs are used in integrated  
circuits or chips that convert e.g. analog video signals  
into a digital format for transmission. The codec also  
converts received digital signals back into analog format.  
A codec uses analog-to-digital conversion and  
Duplex - See Full-duplex.  
DVR (Digital Video Recorder) - A DVR records analog  
video to a hard disk in digital format. Most DVRs use the  
MPEG-2 format for encoding analog video signals.  
Encoder - See Video encoder.  
digital-to-analog conversion in the same chip.  
Ethernet - Ethernet is the most widely installed local area  
network technology. An Ethernet LAN typically uses  
special grades of twisted pair wires. The most commonly  
installed Ethernet systems are 10BASE-T and  
100BASE-T10, which provide transmission speeds up to  
10 Mbps and 100 Mbps respectively.  
Codec can also mean compression/decompression, in  
which case it is generally taken to mean an algorithm or  
computer program for reducing the size of large files and  
programs.  
Composite video - A type of video signal in which the  
red, blue and green signals are mixed together.  
ETRAX (Ethernet Token Ring AXIS) - The ETRAX chip is  
the cornerstone of Axis technology and the 'brain' in  
nearly all Axis products. A multipurpose Linux chip with  
integrated Ethernet networking and extremely flexible I/O  
options.  
Compression - See Image Compression.  
Control unit - If a CCTV system has more than one  
camera, there must be a way to control the video signals  
going to recorders and monitors. There are three basic  
types of Video Control Unit: Multiplexer, Switch and  
Quad.  
Factory default settings - These are the settings that  
originally applied for a device when it was first delivered  
from the factory. If it should become necessary to reset a  
device to its factory default settings, this will, for many  
devices, completely reset any settings that were changed  
by the user.  
DC-Iris - This special type of iris is electrically controlled  
by the camera, to automatically regulate the amount of  
light allowed to enter.  
Decoder - See Video decoder.  
Firewall - A firewall works as a barrier between networks,  
e.g. between a Local Area Network and the Internet. The  
firewall ensures that only authorized users are allowed to  
access the one network from the other. A firewall can be  
De-interlacing - See Interlacing.

how to display the page's words and images for the user.  
HTTP (Hypertext Transfer Protocol) - HTTP is the set of  
rules for exchanging files (text, graphic images, sound,  
video, and other multimedia files) on the web. The HTTP  
protocol runs on top of the TCP/IP suite of protocols.  
Fixed iris - See Autoiris.  
FTP (File Transfer Protocol) - FTP is an application  
protocol that uses the TCP/IP protocols, used to exchange  
files between computers/devices on networks.  
HTTPS (Hypertext Transfer Protocol over SSL) - HTTPS  
is a protocol used by web browsers and servers to encrypt  
and decrypt user page requests and the pages returned by  
the server. The encrypted exchange of information is  
governed by the use of an HTTPS certificate (issued by a  
Certificate Authority), which guarantees the authenticity  
of the server.  
Frame - A frame is a complete video image. In the 2:1  
interlaced scanning format of the RS-170 and CCIR  
formats, a frame is made up of two separate fields of  
262.5 or 312.5 lines interlaced at 60 or 50 Hz to form a  
complete frame, which appears at 30 or 25 Hz. In video  
cameras with a progressive scan, each frame is scanned  
line-by-line and not interlaced; most are also displayed at  
30 and 25 Hz.  
Hub - A (network) hub is used to connect multiple devices  
to the network. The hub transmits all data to all devices  
connected to it, whereas a switch will only transmit the  
data to the device it is specifically intended for.  
Frame rate - The frame rate used to describe the  
frequency at which a video stream is updated is measured  
in frames per second (fps). A higher frame rate is  
advantageous when there is movement in the video  
stream, as it maintains image quality throughout.  
IEEE 802.11 - A family of standards for wireless LANs.  
The 802.11a standard supports 1 or 2 Mbit/s transmission  
on the 5 GHz band. IEEE 802.11b supports data rates up  
to11 Mbit/s on the 2.4 GHz band, while 802.11g allows up  
to 54 Mbit/s on the 2.4 GHz band.  
Gain - Gain is the amplification factor and the extent to  
which an analog amplifier boosts the strength of a signal.  
Amplification factors are usually expressed in terms of  
power. The decibel (dB) is the most common way of  
quantifying the gain of an amplifier.  
Image compression - Image compression minimizes the  
file size (in bytes) of an image. Two of the most common  
compressed image formats are JPEG and GIF. See also  
MPEG and Motion JPEG.  
Gateway - A gateway is a point in a network that acts as  
an entry point to another network. In a corporate network  
for example, a computer server acting as a gateway often  
also acts as a proxy server and a firewall server. A  
gateway is often associated with both a router, which  
knows where to direct a given packet of data that arrives  
at the gateway, and a switch, which furnishes the actual  
path in and out of the gateway for a given packet.  
Interlacing - Interlaced video is video captured at 50  
pictures (known as fields) per second, of which every 2  
consecutive fields (at half height) are then combined into  
1 frame. Interlacing was developed many years ago for  
the analog TV world and is still used widely today. It  
provides good results when viewing motion in standard  
TV pictures, although there is always some degree of  
distortion in the image.  
GIF (Graphics Interchange Format) - GIF is one of the  
most common file formats used for images in web pages.  
There are two versions of the format, 87a and 89a.  
Version 89a supports animations, i.e. a short sequence of  
images within a single GIF file. A GIF89a can also be  
specified for interlaced presentation.  
To view interlaced video on e.g. a computer monitor, the  
video must first be de-interlaced, to produce progressive  
video, which consists of complete images, one after the  
other, at 25 frames per second. See also Progressive scan.  
IP (Internet Protocol) - The Internet Protocol is a method  
transmitting data over a network. Data to be sent is  
divided into individual and completely independent  
“packets”. Each computer (or host) on the Internet has at  
least one address that uniquely identifies it from all  
others, and each data packet contains both the sender's  
address and the receiver's address.  
GOV (Group Of VOPs) - A group of VOPs is the basic unit  
of an MPEG-4 video stream. The GOV contains different  
types and numbers of VOPs (I-VOPs, P-VOPs) as  
determined by the GOV length and GOV structure. See  
also VOP.  
GOV length - The GOV length determines the number of  
images (VOPs) in the GOV structure.  
See also GOV and VOP.  
The Internet Protocol ensures that the data packets all  
arrive at the intended address. As IP is a connectionless  
protocol, which means that there is no established  
connection between the communication end-points,  
packets can be sent via different routes and do not need  
to arrive at the destination in the correct order.  
GOV structure - The GOV structure describes the  
composition of an MPEG-4 video stream, as regards the  
type of images (I-VOPs or P-VOPs) included in the stream,  
and their internal order. See also GOV and VOP.  
Once the data packets have arrived at the correct  
destination, another protocol - Transmission Control  
Protocol (TCP) - puts them in the right order.  
HTML (Hypertext Markup Language) - HTML is the set  
of “markup” symbols or codes inserted in a file intended  
for display in web browser. The markup tells the browser

camera iris must be adjusted manually to regulate the  
amount of light allowed to reach the image sensor.  
IP address - An IP address is simply an address on an IP  
network used by a computer/device connected to that  
network. IP addresses allow all the connected  
computers/devices to find each other and to pass data  
back and forth.  
Mbit/s (Megabits per second) - A measure of the bit rate,  
i.e. the rate at which bits are passing a given point.  
Commonly used to give the “speed” of a network. A LAN  
might run at 10 or 100 Mbit/s. See also Bit rate.  
To avoid conflicts, each IP address on any given network  
must be unique. An IP address can be assigned as fixed,  
so that it does not change, or it can be assigned  
dynamically (and automatically) by DHCP.  
Monitor - A monitor is very similar to a television set, but  
lacks the electronics to pick up regular television signals.  
Motion JPEG - Motion JPEG is a simple  
compression/decompression technique for network video.  
Latency is low and image quality is guaranteed, regardless  
of movement or complexity of the image. Image quality is  
controlled by adjusting the compression level, which in  
turn provides control over the file size, and thereby the bit  
rate.  
An IP address consists of four groups (or quads) of  
decimal digits separated by periods, e.g. 130.5.5.25.  
Different parts of the address represent different things.  
Some part will represent the network number or address,  
and some other part will represent the local machine  
address. See also IP (Internet Protocol).  
High-quality individual images from the Motion JPEG  
Inputs/Outputs (I/Os) - The digital I/Os on, for example, a  
network camera can be used to connect any device that  
can toggle between an open and a closed circuit.  
stream are easily extracted. See also JPEG and GIF.  
Megapixel - See Pixel.  
MPEG (Moving Picture Experts Group) - The Moving  
Picture Experts Group develops standards for digital video  
compression. It operates under the auspices of the  
International Organization for Standardization (ISO). The  
MPEG standards are an evolving series, each designed for  
a different purpose.  
For example, if a door switch is used as an input device,  
opening the door could trigger the upload of video images  
and the sending of notification messages.  
An output might, for example, be used to automatically  
start a siren when there is a motion detection trigger.  
I-VOP - See VOP.  
MPEG-2 - The designation for a group of video coding  
standards, and is typically used to encode video for  
broadcast signals, including digital satellite and Cable TV.  
MPEG-2, with some modifications, is also the coding  
format used by standard commercial DVD movies.  
JPEG (Joint Photographic Experts Group) - Together  
with the GIF file format, JPEG is an image file type  
commonly used on the web. A JPEG image is a bitmap,  
and usually has the file suffix '.jpg' or “.jpeg”. When  
creating a JPEG image, it is possible to configure the level  
of compression to use. As the lowest compression (i.e. the  
highest quality) results in the largest file, there is a  
trade-off between image quality and file size.  
MPEG-4 - MPEG-4 is a group of video coding standards  
and related technology. The primary uses for the MPEG-4  
standard are web (streaming media) and CD distribution,  
conversational (videophone), and broadcast television.  
kbit/s (kilobits per second) - A measure of the bit rate,  
i.e. the rate at which bits are passing a given point. See  
also Bit rate.  
Most of the features included in MPEG-4 are left to  
individual developers to decide whether to implement  
them or not. This means that there are probably no  
complete implementations of the entire MPEG-4 set of  
standards. To deal with this, the standard includes the  
concept of “profiles” and “levels”, allowing a specific set  
of capabilities to be defined in a manner appropriate for a  
subset of applications.  
LAN (Local Area Network) - A LAN is a group of  
computers and associated devices that typically share  
common resources within a limited geographical area.  
Linux - Linux is an open source operating system within  
the UNIX family. Because of its robustness and  
availability, Linux has won popularity in the open source  
community and among commercial application  
developers.  
Multicast - Bandwidth-conserving technology that  
reduces bandwidth usage by simultaneously delivering a  
single stream of information to multiple network  
recipients. See also Unicast.  
Lux - A standard unit of illumination measurement.  
Network camera (Network video camera) - A network  
camera is a camera and computer combined in one  
intelligent unit. It captures and sends live video directly  
over an IP network such as a LAN, intranet or the  
Internet. Users can view and/or manage the camera using  
a standard web browser or application software from any  
local or remote computer on a network. The camera  
allows multiple authorized viewers from different  
MAC address (Media Access Control address) - A MAC  
address is a unique identifier associated with a piece of  
networking equipment, or more specifically, its interface  
with the network. For example, the network card in a  
computer has its own MAC address.  
Manual iris - This is the opposite of an auto iris, i.e. the

locations to simultaneously access images. A network  
camera is sometimes known as an IP camera.  
Network) as a large single LAN (Local Area Network). This  
kind of interconnection is known as a virtual private  
network (VPN).  
Network connectivity - The physical (wired or wireless)  
and logical (protocol) connection of a computer network  
or an individual device to a network, such as the Internet  
or a LAN.  
Pre/post alarm images - The images from immediately  
before and after an alarm. These images are stored in a  
buffer for later retrieval.  
Network video - Network video (often referred to as  
IP-Surveillance for specific applications within security  
surveillance and remote monitoring) is a system that gives  
users the ability to monitor and record video over an IP  
network (LAN/WAN/Internet).  
Progressive scan - Progressive scan, as opposed to  
interlaced video, scans the entire picture, line by line  
every sixteenth of a second. In other words, captured  
images are not split into separate fields as in interlaced  
scanning.  
NTSC (National Television System Committee) - NTSC is  
an analog color encoding system used in television  
systems in Japan, the United States and other parts of the  
Americas. NTSC defines the video signal using 525 TV  
lines per frame, at a refresh rate equal to 30 frames per  
second. See also PAL.  
Computer monitors do not need interlace to show the  
picture on the screen, but instead show them  
progressively, on one line at a time in perfect order i.e. 1,  
2, 3, 4, 5, 6, 7 etc., so there is virtually no “flickering”  
effect. In a surveillance application, this can be critical  
when viewing detail within a moving image, such as a  
person running. A high-quality monitor is required to get  
the best from progressive scan. See also Interlacing.  
NVR (Network Video Recorder) - A dedicated Network  
Video Recorder (NVR) can be used to gather data streams  
from remote network cameras and video servers and store  
them on a hard disk. An NVR can be a standard  
networked PC, or a dedicated video recording hard disk  
server with its own software application.  
Protocol - A special set of rules governing how two  
entities will communicate. Protocols are found at many  
levels of communication, and there are hardware  
protocols and software protocols.  
PAL (Phase Alternating Line) - PAL is an analog color  
encoding system used in television systems in Europe and  
in many other parts of the world. PAL defines the video  
signal using 625 TV lines per frame, at a refresh rate equal  
to 25 frames per second. See also NTSC.  
Proxy server - In an enterprise that uses the Internet, a  
proxy server acts as an intermediary between a  
workstation user and the Internet. This provides security,  
administrative control, and a caching service. Any proxy  
server associated with a gateway server, or part of a  
gateway server, effectively separates the enterprise  
network from the outside network and the local firewall.  
It is the firewall server that protects the enterprise  
network from outside intrusion.  
Ping - Ping is a basic network program used  
diagnostically to check the status of a network host or  
device. Ping can be used to see if a particular network  
address (IP address or host name) is occupied or not, or if  
the host at that address is responding normally. Ping can  
be run from e.g. the Windows Command prompt or the  
command line in Unix.  
PTZ (Pan Tilt Zoom) - A PTZ-enabled camera can be  
remotely controlled so as to change the view from the  
camera. Panning is the movement of the camera along its  
horizontal axis, tilting is the movement of the camera  
along its vertical axis, and zooming is the adjustment of  
the zoom lens to magnify the view.  
Pixel (Picture Element) - A pixel is one of the many tiny  
dots that make up a digital image. The color and intensity  
of each pixel represents a tiny area of the complete image.  
P-VOP - See VOP.  
PoE (Power over Ethernet) - Power over Ethernet  
provides power to a network device via the same cable as  
used for the network connection. This is very useful for  
IP-Surveillance and remote monitoring applications in  
places where it may be too impractical or expensive to  
power the device from a power outlet.  
Resolution - Image resolution is a measure of how much  
detail a digital image can hold: the greater the resolution,  
the greater the level of detail. Resolution can be specified  
as the number of pixel-columns (width) by the number of  
pixel-rows (height), e.g. 320x240.  
PPP (Point-to-Point Protocol) - A protocol that uses a  
serial interface for communication between two network  
devices. For example, a PC connected by a phone line to a  
server.  
Alternatively, the total number of pixels (usually in  
megapixels) in the image can be used. In analog systems  
it is also common to use other format designations, such  
as CIF, QCIF, 4CIF, etc.  
PPTP (Point-to-Point Tunneling Protocol) - A protocol  
(set of communication rules) that allows corporations to  
extend their own corporate network through private  
“tunnels” over the public Internet. In this way a  
corporation can effectively use a WAN (Wide Area  
RS-232 - A long-established standard that describes the  
physical interface and protocol for low-speed serial data  
communication between devices. This is the interface that  
e.g. a computer uses to talk to and exchange data with a  
modem and other serial devices.

RS-485 - An upgraded version of RS-422 that supports  
up to 32 devices on the same connection. RS-485 is an  
electrical specification of a two-wire, half-duplex,  
multipoint serial connection. It enables the configuration  
of inexpensive local networks and multidrop  
limited in its ability to queue messages at the receiving  
end, and is usually used with one of two other protocols,  
POP3 or IMAP. These other protocols allow the user to  
save messages in a server mailbox and download them  
periodically from the server.  
communications links. It offers high data transmission  
speeds (up to 10Mbit/s), and as it uses a differential  
balanced line over twisted pair (like RS-422), it can span  
relatively large distances (4000 feet or 1200 meters).  
RS-485 only specifies the electrical characteristics of the  
driver and the receiver. It does not specify or recommend  
any data protocol.  
SMTP authentication - An extension of SMTP, where the  
client is required to log into the mail server before or  
during the sending of email. It can be used to allow  
legitimate users to send email while denying the service to  
unauthorized users, such as spammers.  
SNMP (Simple Network Management Protocol) - SNMP  
forms part of the Internet Protocol suite, as defined by the  
Internet Engineering Task Force. The protocol can support  
monitoring of network-attached devices for any  
RTCP (Real-Time Control Protocol) - RTCP provides  
support for real-time conferencing of groups of any size  
within an intranet. This support includes source  
identification and support for gateways like video bridges  
as well as multicast-to-unicast translators. It offers  
quality-of-service feedback from receivers to the  
multicast group as well as support for the synchronization  
of different media streams.  
conditions that warrant administrative attention.  
Sockets - Sockets are a method for communication  
between a client program and a server program over a  
network. A socket is defined as “the endpoint in a  
connection”. Sockets are created and used with a set of  
programming requests or “function calls” sometimes  
called the sockets application programming interface  
(API).  
RTP (Real-Time Transport Protocol) - An Internet  
protocol for the transport of real-time data, such as video.  
It can be used for media-on-demand as well as interactive  
services such as Internet telephony.  
SSL/TSL  
(Secure Socket Layer/Transport Layer Security) - These  
two protocols (SSL is succeeded by TSL) are cryptographic  
protocols that provide secure communication on a  
network. SSL is commonly used over HTTP to form  
HTTPS, as used e.g. on the Internet for electronic financial  
transactions. SSL uses public key certificates to verify the  
identity of the server.  
RTSP (Real Time Streaming Protocol) - A control  
protocol, and a starting point for negotiating transports  
such as RTP, multicast and unicast, and for negotiating  
codecs. RTSP can be considered a “remote control” for  
controlling the media stream delivered by a media server.  
RTSP servers typically use RTP as the protocol for the  
actual transport of video data.  
Subnet & subnet mask - A subnet is an identifiably  
separate part of an organization's network. Typically, a  
subnet may represent all the machines at one geographic  
location, in one building, or on the same local area  
network (LAN). Having an organization's network divided  
into subnets allows it to be connected to the Internet with  
a single shared network address.  
Router - A device that determines the next network point  
to which a packet should be forwarded on its way to its  
final destination. A router creates and/or maintains a  
special routing table that stores information on how best  
to reach certain destinations. A router is sometimes  
included as part of a network switch. See also Switch.  
Security surveillance - Network video's advanced  
functionality makes it highly suited to the applications  
involved in security surveillance. The flexibility of digital  
technology enhances security personnel's ability to  
protect people, property and assets. Such systems are  
therefore an especially attractive option for companies  
currently using CCTV.  
The subnet mask is the part of the IP address that tells a  
network router how to find the subnet that the data  
packet should be delivered to. Using a subnet mask saves  
the router having to handle the entire 32-bit IP address; it  
simply looks at the bits selected by the mask.  
Switch - A network device that connects network  
segments together, and which selects a path for sending a  
unit of data to its next destination. In general, a switch is  
a simpler and faster mechanism than a router, which  
requires knowledge about the network and how to  
determine the route. Some switches include the router  
function. See also Router.  
Server - In general, a server is a computer program that  
provides services to other computer programs in the same  
or other computers. A computer running a server program  
is also frequently referred to as a server. In practice, the  
server may contain any number of server and client  
programs. A web server is the computer program that  
supplies the requested HTML pages or files to the client  
(web browser).  
TCP (Transmission Control Protocol) - TCP is used along  
with the Internet Protocol (IP) to transmit data as packets  
between computers over the network. While IP takes care  
of the actual packet delivery, TCP keeps track of the  
individual packets that the communication (e.g. requested  
SMTP (Simple Mail Transfer Protocol) - Used for sending  
and receiving e-mail. However, as it is “simple”, it is

a web page file) is divided into, and, when all packets  
have arrived at their destination, it reassembles them to  
re-form the complete file.  
Video management software - Video management  
software supplies the means for monitoring, analyzing  
and recording network video. In its simplest form, it offers  
live viewing, storage and retrieval of video sequences.  
Advanced applications may also provide support for  
recording of live video from multiple devices, different  
recording modes, search functions, remote access via a  
web browser, control of PTZ devices, etc.  
TCP is a connection-oriented protocol, which means that  
a connection is established between the two end-points  
and is maintained until the data has been successfully  
exchanged between the communicating applications.  
Telnet - Telnet is a simple method with which to access  
another network device, e.g. a computer. The HTTP  
protocol and the FTP protocols allow you to request  
specific files from remote computers, but do not allow you  
logon as a user of that computer. With Telnet, you log on  
as a regular user with whatever privileges you may have  
been granted for specific applications and data residing  
on that computer.  
VMD (Video Motion Detection) - Video Motion detection  
defines activity (motion) in a monitored scene by  
analyzing image data and differences in series of images.  
This detection can, for example, be used to trigger an  
alarm event in a network camera and start the upload of  
images from the camera.  
Video switcher - An analog video switcher sequentially  
displays full screen images, from one camera after  
another, typically at 3-5 seconds intervals. Other camera  
sources are not recorded while the image source from one  
camera is displayed on screen.  
Time-lapse recorder - This type of video recorder is  
commonly used in the security industry and has the  
ability to record up to one week of video on a single tape.  
The most commonly used timing is the 24-hour mode.  
Having to change tapes only once a day and retaining  
large amounts of information are perceived as key  
advantages in using this particular mode of recording.  
VOP (Video Object Plane) - A VOP is an image frame in  
an MPEG-4 video stream. There are several types of VOP:  
- An I-VOP is a complete image frame.  
UDP (User Datagram Protocol) - UDP is a  
- An P-VOP codes the differences between images, as long  
as it is more efficient to do so. Otherwise it codes the  
whole image, which may also be a completely new image.  
communications protocol that offers limited service for  
exchanging data in a network that uses the Internet  
Protocol (IP). UDP is an alternative to the Transmission  
Control Protocol (TCP). The advantage of UDP is that it is  
not required to deliver all data and may drop network  
packets when there is e.g. network congestion. This is  
suitable for live video, as there is no point in  
re-transmitting old information that will not be displayed  
anyway.  
WAN (Wide-Area-Network) - Similar to a LAN, but on a  
larger geographical scale.  
Web camera (Webcam) - A camera that requires a  
constant connection (via e.g. USB) to a PC for its  
operation. See also Network camera.  
Web server - A program that allows web browsers to  
retrieve files from computers connected to the Internet.  
The Web server listens for requests from browsers and  
upon receiving a request for a file sends it back to the  
browser. The primary function of a Web server is to serve  
pages to other remote computers.  
Unicast - Communication between a single sender and a  
single receiver over a network. A new connection is  
established for each new user. See also Multicast.  
UPnPTM - A set of computer network protocols that allows  
the automatic peer-to-peer detection of devices on the  
network. UPnP is promoted by the UPnP Forum.  
Zoom lens - A zoom lens can be moved (zoomed) to  
enlarge the view of an object to show more detail.  
URL (Uniform Resource Locator) - An “address” on the  
network.  
Video camera - See Network camera and CCTV video  
camera.  
Video decoder - A network video decoder converts digital  
video streams back into analog signals, which can then be  
displayed on standard TV sets, analog monitors and video  
switches.  
Video encoder (video server) - A video encoder/server  
digitizes analog video signals and sends digital images  
directly over an IP network, such as a LAN, intranet or the  
Internet. In effect, it turns an analog video system into a  
network video system and enables users to view live  
images using a web browser or application software on  
any local or remote computer on a network.
